About the only thing that counts today as bannable kiddie porn (and this proposed law wouldn’t change it because it became a USSC level constitutional challenge) is material in which photography of actual minors performing actual indecent acts appears. I.e. which can be traced back to the sexual exploitation of minors. That it looks like something unspeakable doesn’t count, if “no children were harmed in the filming of this video” and what looks indecent is something else, like consenting adults, trick photography, animation, computer aided simulation, etc. With ever more powerful photograph and movie editing software now available even for free, “authentic” kiddie porn will likely become a very rare bird, making this a vast overkill. In the meantime, all those dossiers kept by “little brother” will be as vulnerable as any computer database to hackers and crackers.
What I mean is that I have debated liberaltarians online who actually do want to legalize the possession of REAL kiddie porn and lower the “age of consent” to 11 or even abolish it.
